s. B. ZIMMER l METHOD oF GLAZING AND GLAZING STRIP Filed July 22, 1925 Manilow;

be Vpressed out on the surface of the glass forming an upper soft mass 12. The clamping bands 13 are then secured in place pressing the sott mass 12 tirmly against the bands and the mass 11 into close contact with kthe sash.

Y These clamping bands may be made of any siiitable shape and character but I have foundv a Z-shaped section is satisfactory. I form this section having a web 14, with a fiange 15 to be secured to the sash and an outer fiange 16 formed with a fold 17 bent inwardly to give a neat and clear edge 1S. These clamping bands are properly proportioned so that when bolted to the sash as by bolts 19, they firmly engage the outer flange Vof the glazing strip and thus press the strip tightly against the sash. It is preferable. 'to use a slight excess ot. glazing compound so that when the clamping band is firmly pressed into position as shown in Fig. G, some of the compound will be pressed beyond the. edge 18 of the band and beyond 'ing strips and section plates.

the edge of the sash.l the excess being re- .moved with a glaziers knife.

For use at-the muntins I utilize section plates 20 which are of proper width to cover the glazing strips on adjacent panes of glass and allow sufiicient glazing compound to be pressed out of the strips to engage the sash and the lower surface of the section plates. 'The section plates are secured to the muntins by bolts 21 or the like and thus :firmly clamp the edges of two panes to the sash forming a close joint therewith by the glazing compounds. I

I find it satisfactory to Vform a` bevel joint 22 at the corners of the clamping hands slightly spaced apart and to form a Y- shaped joint 23 at the junction ofi the clamp- A variety of corner ends for 'the glazing strips may be utilized. In one type I cut the strips hackwardly on an angle as indicated by 24 in Fig. 7 leaving a corner 25 oi the glass with.- out covering. In another form I cut the ineetingedges of the glazing strips on a. bevel 26 so that they meet with a type of mitre `joint as shown in Fig. 8. A butt joint 27 is illustrated in' Fig. 9. It will be un -derstood that whatever type ot joint is used for the cornersof the glazing strips a slight Vsuch cases I may utilize a curved strip spaceshould he left to allow the edge of the glass to bepressed close to the web of the glazing strip.

In some constructions it is advisable to compress the webs ot the glazing strip. In as illustrated in Fig. 10 in which the wehs 28 are spaced by a curved section 29 so that the glazing compound can be pressed out and the webs may be pressed close to the pane of glass.

The details of the particular type of glazing strip, the manner ot using a glazing composition therein and ot torcing this composition out of the glazing strip by the manner of pressing or clamping the strip to a frame may be considerably changed to suity special circumstances without departing from the spirit of my invention. Also other types ot clamping hars and section plates may be used and although l have illustrated my invention as applied to a [lat snr'l'ace sash it may be used with ditl'crent shapes and with fancy glasses or panes.

Having described my invention. what I claim is:

1. The method ol glazing, comprising partially filling channel-shaped glazing strips with a soft glazing coilipositiw, pressing said strips slightly on the peripheral edges of a pane of glass. positioning thc pane with the strips on a sash to bc glazed. firmly pressing the strips towards thc glass to force the glazing composition front the base of the strips around the sides ot the glass and clamping the strips and hence. the glass to the sash.

2. The method of glazing, comprising placing a glazing composition in channelshaped glazing strips. embedding a pane of glass partially in the composition by pressing the peripheral edges slightly therein, further pressing the glazing strips on the glass to force the glazing composition along the sides of the glass to completely fill the glazing strip and allowing some of the glazing composition to be pressed beyond the strip, securing a clamping bar to the sash to press the outer portion ot the glazing strip and the glazing composition exuded therefrom against the glass and against the sash.

3. A glazed sash` comprising in combination a sash, a pane of glass having glazing strips in the form ot channels with a glazing composition therein secured to the edges of the pane with the glazing composition covering the edges and a portion of both sides of the glass completely spacing the glass from the channel and means to secure the channel to the sash.

4. A glazed sash, comprising in combination a sash. a pane of glass having a plurality of glazing strips in the form oi channels having webs and outstanding flanges, with a glazing composition therein secured to thc peripheral edges of the pane. a securing plate positioned against onepf the fianges of the channel and cmeans lo press the other flange tightly against the sash whereby the glazing composition secures the pane spaced from the web and from hoth flanges and with the glazing composition contacting with the sash both. faces of the glass and the securing plate.

5. A glazed sash as claimed in claim f1,

til)

in which the securing plate has a web portion, an outer flange en aging the outer flange of the channel and an inner flange positioned against the sash with means to secure said inner flange to the sash.

6. A 0lazed sash as claimed in claim 4, in whici the secu-ring late comprises an angularly bentstrip ofl metal having an opstanding web slightly deeper than the web of the channel, an upper flange formed with a reverse inward fold of' the metal and an inner flange in contact with the sash with means to secure the inner flange to the sash.

7 A glass sash colnprising in combination a` sash, a series of panes of glass each having glazing strips substantially channel-shaped with a glazing composition therein secured to the peripheral edges ot' each pane, clamping bands of angular shape having flanges secured to the sash, opstanding webs and outer flanges engaging the glazing strips and flat section plates engaging the edges ofi thc strips on two aflirifcntpanes and means to secure said section plates to muntins of the sash.

8. The method of glazing, comprising inserting a glazing strip of small channelshape with a soft glazing com osition therein on the edge of a pane of g ass, clamping the strip to a sash whereby the strip is deformed in shape and the glazing com osition forced partly along the sides o' the pane.

9. In combination a glazing strip formed of a somewhat channel-shaped strip of material, a` glazing composition therein. a pane of glass with an edge positioned in the strip and in contact with the glazing composition and means to secure the strip to a sash deforming the same to thereby press the composition into Contact with a. portion of the sides and edge of the glass and with the sides of the strip.

In testimony whereof I have signed my name to this specification.
